Ironic quote in the sub-headline
...considering that Moore's original observation referred to lowering the cost of transistors. Here's a quote from his 1965 paper (see e.g. https://montcs.bloomu.edu/~bobmon/PDFs/Gordon%20Moore.Law.pdf)
The complexity for minimum component costs has in-
creased at a rate of roughly a factor of two per year (see
graph on next page). Certainly over the short term this rate
can be expected to continue, if not to increase. Over the
longer term, the rate of increase is a bit more uncertain, al-
though there is no reason to believe it will not remain nearly
constant for at least 10 years. That means by 1975, the num-
ber of components per integrated circuit for minimum cost
will be 65,000.
I believe that such a large circuit can be built on a single
wafer.
